STOVE OR FURNACE.

SPEGIFIGATIONforming part of Letters Patent No. 605,519, dated June 14, 1898. Application filed IEebruaryZS, 1897. Serial No. 624,674. (No model.)

To all whom it may concern:

Be it known that I, VVALLAOE J. SELBY, a citizen of the United States, residing at Burr Oak, in the county of St. Joseph and State of Michigan, have invented a new and useful Stove or Furnace, of which the following is a specification.

This invention relates to certain improvements in stoves and furnaces and other heating devices, and has for its object to improve and simplify the construction of the base and fire-pot of the stove or other device, so as to provide a simpleand practical arrangement of these parts, together with the ash-fines and ash-chamber, so as to enable the ashes to be removed from the stove or other heating device in a convenient and satisfactoryway.

The invention consists in a heating device having a base and a fire-pot and provided with a diving-flueleading from the fire-pot down into and through the baseand communicating with the outlet to the chimney, an ash-passage leading from the lower part of the fire-pot across the flue in the base, and means to collect the ashes in said passage.

The invention also consists in certain novel features of the construction, combination,

and arrangement of the various parts of the improved heating device, whereby certain important advantages are attained, and the device is made simpler, cheaper, and otherwise better adapted and more convenient for use, as will be hereinafter set forth.

The novel features ofthe invention will be I plan view showing the diaphragm extending across the base and dividing the ash-chamber from the diving-flue, and also ;-showing the sliding plate for closing the ash-passage from the fire-pots between said curved edges of the partition or diaphragm being provided with upturned flange-s 6 to receive rivets or equivalent fastening devices for securing the diaphragm in place within the shell. The diaphragm 5 is alsoprovided with straight-edge portions 8, located between the curved portions and also provided with upturned flanges, outside of which are formed seats 8 By this formation of the diaphragm 5 it will be seen that when said diaphragm is in place in the shell spaces or openings will be formed at opposite sides of the shell, these openings or spaces extending between the walls of the shell and the straight edges 8 of the diaphragm.

7 indicates a Vertical partition, the lower edge of which rests upon the seat 8 at one edge of the diaphragm 5, said partition 7 extending entirely across the shell 3 and standing vertically, so as to form a diving-flue 10 partition and the adjacent wall of the shell 3. 1

The upper edge of the partition 7 is provided with an overturned or bent portion 9, as indicated in Figs. 1. and 2, this bent portion being formed in the nature of a grating,

asclearly shown, preventing the fuel from passing into the flue 10. Near its lower part the partition 7 is provided with a circular opening 7 which-is adapted for communication with a flue 11, extending transversely across the diving-flue 10 and having its outer end adapted to receive air from outside the shell 3. A damper or flange 12 controls the fluell, as, clearly shown in Fig. 1. At the edge 8 of the diaphragm 5,0ppositeto' the partition 7, is arranged a vertical partition 13, similar to the partition 7, but extending up to the top of the shell 3 and being-vertical throughoutits whole length. Thelower end of the partition 13 rests upon the seat 8 and is riveted to the upturned flange on the diaphragm5, as indicated in Figs. 1 and 2, and said partition 13 forms between it and the adjacent wall of the shell 3 a Vertical flue 15, parallel with the diving-flue 10, but arranged at the opposite side of the shell and extending to the top of the stove, where it connects with the flange 16, which receives the stovepipe.

Below the diaphram'5 is arranged a similar diaphragm 19, which extends across the rectangular base 1 of the stove, said diaphragm 19 being made for this purpose also rectangular in form, as shown in the drawings, and V the space 20 between the two diaphragms 5 and 19 forms a flue extending transverselyor' horizontally across the base 1 of the stove, beneath the fire-pot, affording communication between the diving-flue 10 and the flue 15, which connects with the smoke-outlet 16, and in the diaphragms 5 and 9 are formed corresponding openings located centrally with respect to the shell 3 of the stove, the upper diaphragm 5 being provided with a depending annular flange 17, surrounding the circular opening in said diaphragm and of sufficient width to extend across the flue 20 and engage at its edge in the circular opening in the lower diaphragm 19, as clearly shown in Fig. 1. I

The edge of the diaphragm 5, surrounding the circular opening at the center of said diaphragm, is formed with a seat 17, adapted to receive the edges of a circular grate 18, on which the fire is supported, the space within the shell 3, between the partitions 7 and 13, forming in reality the fire-pot of the stove, and the ashes from said fire-pot being adapted to pass through the bars of the grate 18 and down through the ash-passage formed within the annular flange 17, at the lower end of which is arranged means to receive and collect the ashes, which I will now describe. 21 indicates a slide-plate arranged to move or slide along the under side of the lower dia phragm 19 and of sufficient dimensions to close the lower end of the ash-passage 17 1 when moved across the same, said slide-plate I being held at its edges in parallel guides or ways 22, secured to the under side of the diaphragm 19 at opposite sides of the centralopening therein. The slide-plate 21 is provided, as shown in Fig. 3, with an operatinghandle 21 on its under side, and beneath the diaphragm 19 is formed an ash-chamber 23, adapted toreceive an ash-pan 24, removably arranged therein and adapted to be passed into said chamber through a door 25, formed at one side of the base 1 and provided with a fastening device of any preferred kind, as indicated at 26 in Fig. 1. By this arrangement it will be seen that when the fire is kindled in the fire-pot the ashes from the fuel will fall into the ash-passage 1'7 and may be collected in the ash-pan 24, arranged below the flue 20 in the base, and it will also be seen that the slide-plate 21 will serve as a convenient means for regulating the air supplied from the ash-chamber through the ash-passage and grate to the fire-pot, it being possible, when desired, to completely cut off the supply of air through these passages whenever desired, and it being also possible by moving the slide-plate across the ash-passage 17 to prevent ashes from falling into the ash-chamber while the ash-pan is removed.

The air-flue 11 will serve for the supply of air to the fire-pot when the passage 17 is closed by means of the slide-plate 21, it being possible to regulate the supply of air through said flue by means of the damper or Valve 12, according to requirements, and in order to 'Tegulate the draft through the outlet-flue 15 I have provided an opening at the upper part of the partition 13, said opening being closed by a damper or valve 27, mounted on a rod 28, carried in perforated lugs 29 on the partition, as shown in Figs. 1 and 2, said'rod havinga bent end adapted to extend outside of the shell 3 of the stove to permit the valve 27 to be opened or closed, so as to permit or prevent the passage of gases from the fire-pot directly to the outlet-flue 15.

From the above description it will be seen that the device constructed in accordance with my invention is of an extremely simple and inexpensive nature, and is especially well adapted for use as aheating-stove, since the arrangement of the fiues permits of conveniently regulating the radiation of heat, and the arrangement of the ash-passage permits the ready removal of the ashes from the firepot.

It will also be evident from the above description that the invention is susceptible of some modification without material departure from its principles and spirit, and for this reason I do not wish to be understood as limiting myself to the precise form and arrangement of parts herein set forth.

Having thus described my invention, I claim 1. 'A heating device comprising a base pro- -IIO vided with a horizontal diaphragm 19, the shell mounted upon the base, the horizontal diaphragm 5 arranged within the shell at the bottom thereof and located above the diaphragm 19 said diaphragm 5 terminating short of the sidesof the shell, the short vertical partition 7 extending upward from one side of the diaphragm 5, forming a flue and provided at its upper end with a grating, the vertical partition 13 located at the opposite side of the diaphragm 5 and extending to the top of the shell and forming a fine between it and the latter, said partitions 7 and 13 and the shell forming a fire-pot between them, and the depending annular flange 17,1ocated in the space between the diaphragms 5 and 19 and connected phragln 19 and terminating short of the sides of the shell, partitions extending npward from the diaphragm 5 and forming with the shell a fire-pot, and the depending annular flange 17 located in the space between the diahra ms 5 and 19 and. formin a communica tion between the base of the stove and the fire-pot, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in [O the presence of two witnesses.
